The postoperative survival rate analysis of elderly patients with hip fracture

Abstract

Objective To study the postoperative survival rate of elderly patients with hip fracture at different time and its related factors. Methods We conducted the follow-up studies of 255 elderly hip fracture patients from June 2008 to June 2011 in our hospital. The survival rates of patients at 6 months, 1, 2 and 3 years after operation and their related factors were studied. Results The survival rate was 96.5%, 89.8%, 78.0% and 69.4% at 6 months, 1, 2 and 3 years after operation respectively in 255 elderly hip fracture patients. Survival analysis showed that many kinds of preoperative comorbidities, low albumin level, old age and severe anemia were the risk factors for survival. Good activity of daily living before injury was a protective factor for survival. Gender, fracture type, the American Society of Anesthesiologists (ASA) classification, time from injury to surgery, anesthesia type, surgical approach, operative time, blood loss and hospital stay periods had no effect on survival after operation. Conclusions The survival rate in elderly patients with hip fracture after surgery is affected by many factors. Preoperative comorbidities, anemia and hypoalbuminemia should be actively treated, the activity of daily living should be improved by the directed therapy and rehabilitation, in order to improve the survival rate in elderly patients with hip fracture.
